i WINDOW Loox.

Application filed June 18, 1925. `58111211110.:V 38,043.

and State of Ohio, have inventcd certain.

ncwand. useful.lmprovements in Window Locke; and I do declare thefollowing to be a full,.clear,,zand eiiact description ofthc.'invention, such as will enable others skilled in the art to which it.appertains to make and use the same.

My inventionzaims vto provide an ,exceptlonally simple and inexpensive,yet an efiicient and desirable device which is'adapted forquick and easyapplication to a window.

and may be used for holding the upper and lower sashes in anydesiredrelatively adj usted positions.

The device comprises in general, a guide member adapted to be mounted onthe upper rail of the lower window sash, and a wedgc sliclably engagedwith said guide member, further objects being to provide a wedge and aguide member of unique construction, and to make novel provision forholding the wedge in an inoperative position when its use is notdesired.

T/Vith the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing.

Figure 1 is a perspective view showing the application of the invention.

Figure 2 is a Vertical sectional view illustrating the wedge'inoperative position in full lines and by dotted lines showing itsinoperative position. v

Figures 3 and 11 are perspective views of the wec ge looking indifferent directions.

Figures 5 and 6v are perspectiveviews of the guide member looking indifferent directions. V

The drawing above briefly described may be considered as illustra-tingthe preferred .form of the invention and while the construction shownwill be hereinafter rather specifically described, it is to beunderstood at the outset that within the scope of the invention asclaimed, modifications may be made.

The numeral 1 designates in a general way, a wedge guiding member. Thismember comprises a substantally Vertical plate .2 having a Vcentral neck3 projecting upwardly from .its upper edge, said neck. being ;providedwithoppositely projecting fingers Al. The end portions 5 of the upperedge of .the plate 2, forn'i shoulders at opposite sides of theneck 3for a purpose to be heremafter' cxplained, and at the ends of theseshoulders, lugs 6 are bcnt laterally from one side of the plate. Theupper. end of the ncck 3 is preferably curved in the same direction inwhich these lugs entend, as shown, and the. =lower end of theplatc 2 hasbeen shown bent in this samedirection to provide a horizontal .led'e 8.eVertical wings 9 Dro'ect in the o J- posite directionfrom the :plate 2,at the vertical edges of the latter, the-lowerends of these wings beingbent latorally inward to provide attaching feet 10 which are= adapted tobe secur-ed by screws or Vthe like 11 tO the upper rail 12 of a lowerwindow sash.

The entire guide member 1 is preferably stamped from a single piece ofsuitable gauge sheet metal, as will be clear from the drawing.

At 13, I have shown a hollow wedge formed of sheet metal, one side wallofsaid wedgebeing produced by inwardly bending a pair of fianges 14;from two adj acent side walls, as shown, a space being left between thetwo flanges, forining a longitudinal slot 15. There is also an openspace 16 between i? the upper ends of the flanges 14. and the upper endof the wedge. slidably engage the Shoulders 5, and the neck 3 passesthrough thelslot 15, the fingers 4' then slidably engaging the innersides of said flanges. In this connection, it Vmay be explalned thatthese fingers are passed through the opening 16, when assembling thedevice. In addition to the guiding influence exerted by the fia-nges 14,neck 3, fingers ll and shoulders 5, it 'ill be seen that the lugs 6embrace the wedge 13 to further guide the same. The side of the wedge,opposite the flanges 14;, is preferably provided with spurs 17 outwardlystamped therefrom to engage one of the side rails of an upper sash, whenthe wedge is in the operative position shown in Figs. 1 and 2. However,when the use of this wedge is not needed, it may be raised and its lowerend 18 then engaged with the ledge 8 as shown in dotted lines in Fig. 2.The wedge is held in either position, against accidental upwardmovement, by a coiled tension spring 19 whoselower end is connectedtothe neok 3 while its upper end is The fianges 14 l suitably connectedto the upper end of the Wedge, the latter being` preferably providedWith a tongue 20Vfor this purpose.

Normally, it may be considered that the wedge 13 occupies the dottedline position of Fig. 2, so as torpermit free sliding of the sashes.7lien they have been relatively adjusted however, the Wedge may beeasily inoved off of the ledge 8 so that the spring` 19 snaps itdownward into operative position, thus eifectively looking both sashes.

On account of the advantages existing for the details shown, they arepreterably followed7 but as above stated, n'iodifications may be madeWithin the scope of the Vinvention as claiined.

I cla'iin:

1. A sash fastencr comprising a guide member adapted to he secured tothe upper rail of a lower sash, said guide n'i-emher having` a. ledge,and a spi'ing-lo\i"e1'ed Wedge slidably engaged With said guide member,said Wedge being' adapted to bd tilted and disposed ou said ledge whennot in use, Whereby it is hold against lo\\"n\vard moveinent.

2. A sash fastener comprising a guide member adapted to he secured tothe upper rail of a lower sash, said guide member having an upstandingnecl: and horizontal Shoulders at opposite sides thereof, said neckbeing` provided With oppositely projecting fingers spaced from saidShoulders,V and a hollow VWedge having a longitudinalV slot in one sideWall through which vsaid neck passes, the aforesaid Shoulders engagingthe outer side of said Wall and said fingers engaging the inner sidethereof.

3. A sash fastener coinprising` a substantially Vertical sheet metalplate having,` Wedge-guiding` means at its upper end, the lower end ofsaid plate being bent horizontally to provide a ledge at one side of theplate, Vertical Wings bent la-terally froin the plate and projectingfrom the other side thereof, said Wings having' horizontally bent lowerends forming attaching feet, a Wedge slidahly engaged with said Wedgeguiding means and adapted to rest on said ledge when not in use, andspring means connectinf; said Wedge and plate and exerting a downwardStress on the former.

In testimony Whereof I have hereunto affixed my signature.
